JAUNDICE DIAGNOSIS PATCH, PATCH AUTHENTICATION SYSTEM, AND JAUNDICE DIAGNOSIS METHOD USING THE SAME

As a method for diagnosing jaundice of a user based on an image by a jaundice diagnosis device, a jaundice diagnosis image is obtained including a jaundice diagnosis reference device divided into a first area and a second area, and a specific body part of a user located in the first area. The identification information of the jaundice diagnosis reference device inserted in the second area is extracted, and validity authentication of the identification information is requested through an interlocked authentication system. When the validity authentication success message is received from the authentication system, the user is diagnosed with jaundice based on the image of a specific body part located in the first area and the jaundice diagnosis comparison image included in the second area.

MAGNETIC RESONANCE IMAGING OF GLYCOGEN AND OTHER POLYSACCHARIDES BY MAGNETIC COUPLING WITH WATER

Some embodiments provide a method for magnetic resonance imaging of polysaccharide molecules, that includes providing a magnetic field that is sufficiently homogeneous over an imaging volume, generating a spatial encoding in the magnetic field, and acquiring one or more water proton signal intensity measurements at each of multiple voxels within the imaging volume. The signal intensity measurements are acquired at one or more irradiation frequencies at lower parts-per-million (ppm) than a baseline frequency associated with free water protons. The method includes generating, based on the water proton signal intensity measurements in each voxel, a water proton signal intensity map of the relayed Nuclear Overhauser Effect (rNOE) exchange process of aliphatic protons in the polysaccharide molecules to free water protons in the imaging volume, and generating, using a calibration of the water proton signal intensity measurements for the rNOE exchange process, a concentration map of the polysaccharide molecules in the imaging volume.

Deep-learning-based cancer classification using a hierarchical classification framework

An automatic classification method for distinguishing between indolent and clinically significant carcinoma using multiparametric MRI (mp-MRI) imaging is provided. By utilizing a convolutional neural network (CNN), which automatically extracts deep features, the hierarchical classification framework avoids deficiencies in current schemes in the art such as the need to provide handcrafted features predefined by a domain expert and the precise delineation of lesion boundaries by a human or computerized algorithm. This hierarchical classification framework is trained using previously acquired mp-MRI data with known cancer classification characteristics and the framework is applied to mp-MRI images of new patients to provide identification and computerized cancer classification results of a suspicious lesion.

Systems and methods for peripheral nervous stimulation for metabolic and endocrine function

Systems and methods are provided for neuro stimulation. In one implementation, a system is provided that includes a stimulator introduced into tissue at a target location and a central controller that communicates wirelessly with the stimulator. The stimulator includes a power system that receives wireless energy transmission, and an electrode system that transmits an electrical pulse for stimulating the target location. The central controller includes a power system that wirelessly delivers power to the stimulator, a communication system that wirelessly communicates with the stimulator, and a processing system that controls the power system and the communication system. The central controller may instruct the stimulator to transmit one or more electrical pulses to the target location to affect an endocrine function (e.g., affect the glucose level of a patient).
